Abstract
A method an apparatus for analyzing biomolecules is described. The method includes injecting and storing one species of ionized molecule in a linear ion trap and injecting second species of oppositely polarity ionized molecule such that the second species is transmitted through the stored first species. The resultant reaction products may be analyzed by a mass analyzed taking account of the remaining charge values. In an aspect, a linear ion trap may be used as the reaction volume, and the ionized species injected along the axis of the trap in a substantially collinear manner. The mass analysis may be performed by mass selective axial ejection or by a mass spectrometer.
